Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the creation action but fails to detail critical aspects like required permissions (e.g., edit access to the spreadsheet), whether the operation is idempotent, error handling for invalid names or ranges, or the impact on existing named ranges. This leaves significant gaps for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded and wastes no space, making it easy to parse quickly while conveying the essential function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has an output schema, so the description doesn't need to explain return values. However, as a mutation tool with no annotations and incomplete parameter documentation (50% schema coverage), the description should provide more context on behavior, usage, and parameters to be fully complete. It's minimally adequate but has clear gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%, with only 'name' and 'range_name' having descriptions in the schema. The tool description adds no additional parameter semantics beyond what the schema provides, such as explaining 'user_google_email' or 'spreadsheet_id'. Given the partial schema coverage, the baseline is 3, as the description doesn't compensate for the undocumented parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Create a named range') and purpose ('that can be referenced by formulas'), which is specific and distinguishes it from other spreadsheet tools like 'format_sheet_range' or 'modify_sheet_values'. However, it doesn't explicitly differentiate from potential siblings like 'manage_sheet_tabs' in terms of named range functionality, keeping it at 4 rather than 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, such as when to create a named range versus using direct cell references or other spreadsheet tools. It lacks context about prerequisites, dependencies, or typical scenarios for application, offering only a basic functional statement.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
